Inspiration and Authority in the Middle Ages 
Prophets and their Critics from Scholasticism to Humanism

Inspiration and Authority in the Middle Ages rethinks the role of prophecy in the Middle Ages by examining how professional theologians responded to new assertions of divine inspiration. Drawing on fresh archival research and detailed study of unpublished manuscript sources from the twelfth to fourteenth centuries, this volume argues that the task of defining prophetic authority became a crucial intellectual and cultural enterprise as university-trainedtheologians confronted prophetic claims from lay mystics, radical Franciscans, and other unprecedented visionaries. In the process, these theologians redescribed their own activities as prophetic by locating inspiration not in special predictions or ecstatic visions but in natural forms of understanding and inthe daily work of ecclesiastical teaching and ministry. Instead of containing the spread of prophetic privilege, however, scholastic assessments of prophecy from Peter Lombard and Thomas Aquinas to Peter John Olivi and Nicholas Trevet opened space for claims of divine insight to proliferate beyond the control of theologians. By the turn of the fourteenth century, secular Italian humanists could lay claim to prophetic authority on the basis of their intellectual powers and literary practices. From Hugh of St Victor to Albertino Mussato, reflections on and debates over prophecy reveal medieval clerics, scholars, and reformers reshaping the contours of religious authority, the boundaries of sanctity and sacred texts, and the relationship of tradition to the new voices of the Late Middle Ages.
